000004544 520__ $$2eng$$aUnder seismic action, asymmetric building can undergo severe damages as a result of the induced torsion phenomenon. The influence of the uncertainties of input parameters, such as seismic intensity (I<sub>a</sub>), peak ground acceleration, mean period and output ones such as, structure top displacement (Drift) and dynamic eccentricity upon the torsion is investigated. 
For this study, two kinds of reinforced concrete building are considered with rigid slab and frame columns. The first one is a symmetric building and the second one is asymmetric. This is in order to compare the torsion effect propagation uncertainties in the two cases. Using a finite element code, dynamic linear and non linear time analysis and pushover analysis have been performed, based on 116 seismic records with a magnitude varying between 6.2 and 7.7. 
The results of this study show that correlation between input parameters and the response of the structure do exist. So, the torsion phenomenon reduces the strength in terms of capacity and increases the vulnerability of the structure under different seismic hazards.
